An island located in the Caribbean Sea, Saint Croix is a county and constituent district of the United States Virgin Islands, an unincorporated territory of the United States. It is the largest of the islands in the territory. The waters around this island are warm all round the year making it an excellent destination for water sports including sailing, scuba diving, kite surfing, snorkeling, paddle boarding, parasailing, kayaking, fishing, and jet skiing. The most popular underwater sites for scuba diving at Saint Croix are the Frederiksted Pier and the drop-off into deep water at Salt River Bay National Historical Park and Ecological Preserve. Moreover, Frederiksted has well-maintained its Victorian era architecture and original seven street by seven street city design and is home to a number of imposing historic structures. Although St. Croix is certainly a 21st century region, with only a little effort travelers can easily step back into its rich past.
